Title: Production of neutralized material having high bulk density
Inventor: IMAMURA MASAKI
IPC: C01G9/02
Filed: 1996-03-01
Abstract: PROBLEM TO BE SOLVED: To obtain a neutralized material having a high bulk density from a solution containing zinc by preadding zinc oxide to the solution and then raising the pH to a specific value or above when neutralizing the solution containing the zinc. SOLUTION: Zinc oxide is preadded to a solution containing zinc and the pH thereof is then raised to >=9.5 when neutralizing the solution containing the zinc. The amount of the zinc oxide added at that time is preferably 0.03-1 expressed in terms of zinc oxide/zinc hydroxide (weight ratio) based on the amount of zinc in the solution and the pH thereof is preferably raised to 10.0-12.0. For example, various amounts of the zinc oxide (having 80μm average particle diameter) are added to 1.0L solution containing zinc sulfate in an amount of 1.0g/L expressed in terms of zinc and the pH thereof is then regulated to 10.5 by using Ca(OH)2 to precipitate the zinc. After completing the reaction, pH is reduced to 9.5 by using sulfuric acid and a nonionic flocculant is added in an amount of 0.35g/m<3> thereto.  The resultant mixture is allowed to stand for 24hr to determine the volume occupied by the neutralized material in the aqueous solution and the amount of the neutralized material. Thereby, the slurry concentration is calculated.

Title: Generation of silicon nitride film
Inventor: HIRABAYASHI ATSUO
IPC: H01L21/318
Filed: 1990-02-26
Abstract: PURPOSE:To generate a silicon nitride film close to a stoichiometric composition by a method wherein polycrystalline silicon is used as a target, an electric discharge is generated in a mixed gas of nitrogen and argon by setting a partial pressure ratio of nitrogen at 40% or higher and a magnetron sputtering operation is executed. CONSTITUTION:Polycrystalline silicon is used as a target; an electric discharge is generated in a mixed gas of nitrogen and argon by setting a partial pressure ratio of nitrogen gas or nitrogen at 40% or higher. That is to say, when the polycrystalline silicon is used as the target and a magnetron sputtering operation is executed by using N2 gas or a mixed gas of N2 and Ar, a composition of a generated film is approached to Si2N4 when a film formation temperature is 200 deg.C or lower and the partial pressure ratio of N2 is set at 40% or higher. Thereby, a silicon nitride film which is not coupled with hydrogen atoms deteriorating a characteristic of a semiconductor device can be generated at a low temperature close to room temperature without using a dangerous gas such as SiH4, NH3 or the like.

Abstract: PURPOSE:To have stable electron emission in good performance for a long period of time under a low temperature by forming a thin film consisting of a specified substance over the electron emitting surface under certain conditions, wherein the electron emitting surface is obtained by impregnation of an electron emitting substance. CONSTITUTION:A porous base body consisting of a high melting point metal such as W or Mo is impregnated with an electron emitting substance, and over the electron emitting surface thus obtained, a thin film is formed which consists of admixture of W with at least one of Sc, Y, Al, Ca or oxide of a metal chiefly containing them. The formation of such a film is accomplished by; (i) sputtering in the atmosphere in which W is not oxidized, but only metal such as Sc etc., is oxidated, of (ii) by first sputter forming the film and then heating it in H or in an atmosphere containing H. Accordingly W is in substantially perfect metal state in the film, and the oxide of metal such as Sc is held in substantially perfect oxidated state, and thus a good electron emitting characteristic is obtained.

Title: Soot blowing method and soot blower
Inventor: MARUOKA YOSHIHIRO
IPC: F23J3/02
Filed: 1981-03-28
Abstract: PURPOSE:To achieve a wide range and strong  soot removing effect by a method wherein a pressurized fluid is exploded by blowing the fluid into an exhaust heat collecting device in a moment so that soot in the device is removed due to a drastic change of the atmosphere in the device which takes place at the time of explosion of the fluid. CONSTITUTION:A plurality of soot blowers B are fixed to the tubular outer wall of the exhaust heat collecting device in such a manner that the secondary side II of each of the blowers opens in the interior of the device and the primary sideIthereof is connected to each of pipes 5 for the pressurized fluid such as steam. Further, each of the pipes 5 on the primary side of the blower B is attached with a control valve which is opened and closed manually or automatically. Thus, when the pressure on the primary sideIof the blower overcomes the pressing force of a pressure spring 3, the valve is opened so that a large quantity of the high pressure fluid flows into the secondary side II of the blower in a moment to thereby induce in the exhaust heat collecting device an explosion required for removing the soot. In this case, the duration of time in which the control valve is opened could be extremely short because it is sufficient for the valve to be opened for a period of time in which the exposion of the fluid takes place.
